Portable Globe Creation for a Geographical Information System

Abstract

Portable globes may be provided for viewing regions of interest in a Geographical Information System (GIS). A method for providing a portable globe for a GIS may include receiving a selected region corresponding to a geographical region of a master globe. The method may further include organizing geospatial data from the master globe based on the selected region and creating the portable globe based on the geospatial data. The portable globe may be smaller than the master globe and include greater geospatial data for the selected region than for the remainder of the portable globe. The method may include transmitting the portable globe to a local device that may render the selected region at a higher resolution than the remainder of the portable globe in the GIS. A system for providing a portable globe may include a selection module, a fusion module and a transmitter.
